Just noticed this on Shiv's PROcede Forum; looks like all is good with the Progman V.25 s/w update, even with the PROcede installed...

"You could leave the ECU in there without any problem. BMW updates the ECU from the OBDII port inside the car. They do know inspect the ECU compartment (where the PROcede is located). But if you want to play it 1000% safe, go ahead and remove it. The update will have no effect on the PROcede if you leave it in or take it out. Nothing to worry about."
